An isolation procedure is at the core of any permit to work system, requiring rigorous application and an intolerance of abuse. I am not a fan of isolation systems which solely use tags. I favour locks while acknowledging that locks can be difficult (but not impossible) to manage offshore, where the configuration and location of valves can prove challenging. Tagging systems rely on the successful application of the paperwork which can break down during periods of high workload (e.g. a shut-down) where multiple permits are being issued, suspended, reissued and cancelled over several days or weeks. My favoured method is the “Lock Box” system. This gives control of the field isolations to both the permit issuer (PI) and the permit receiver (PR), but not to each individual working under the permit (see later) and provides a physical barrier in addition to the paperwork.

It is accepted that others may have different views and be committed to their own system.
